What are you on about? We live on Earth and can't survive 1 second without it's resources. The rest of the universe is completely irrelevant.
We agree that retrieving stolen property from a thief is fine but what if the thief had already sold your property and you're taking it back from someone who purchased it? This is a realistic scenario because thieves usually look to move stolen goods as quickly as possible. Is that stealing?
If you just take your car, the guy will call the police, you will be arrested then if you will be able to prove that it was your car, you will not be charged. The guy who bought the car was defrauded, police will investigate and eventually will get to the thief. It is not a good idea to take law into your own hands and go out and take your stolen stuff. Just call the police, tell them that you located your stolen car and let them handle it. That is why we pay taxes. Let the police do their job.

If you just go out and take your stuff, you know that you will be arrested and if you resist, police can shoot you, either way, you end up either dead or in jail. There is where all criminals belong, IMHO.
BTW, redistribution of wealth accomplishes nothing, it creates a short-term relief for the unfortunate and/or lazy and poor, then the class structure forms again, and the wealth pyramid is rebuilt again. Capital is wasted. Time is lost. Millions die in the process. What forms during such revolutionary periods is much worse than what was there before. Study French and Bolshevik revolutions. Be careful what you wish for.
I have lived under the Communist regime. I know better than you what that system does to your psyche, your motivation, your ambitions. That system kills all innovation, desire to improve your life, it is the most destructive system human mind ever invented.
I do understand why you are fooled by the slogans. You want equality, fairness, equal chances for everyone. Those are great goals. But you are forgetting about one thing. Humans are not all the same. We are not ants. We all have different skills, abilities, ambitions, and aspirations.
Some of us worked hard to learn to speak 8+ languages fluently, have multiple graduate degrees, achieved great success in business and accumulated some wealth as a result. While others can barely speak and write in their own native language, have no post-secondary education, skill or trade, and on top of that are lazy and want to take stuff from the "rich" people. How is it fair for the "rich" people to be robbed by the imbeciles? Just think about what you are proposing. Think about the long-term consequences. Study history. Don't ignore it.
Conveniently, you chose to talk about the one piece of property police keep record of, but what about everything else? What if you can't provide proof that it is your property to the police but you know that it is your property? Do you still consider this stealing?
I hope you also realize that redistribution of wealth is also often done through legal means. By your logic, this is not stealing because if the government taxes me, I cannot call the government and tell them that the tax money belongs to me and have them return it. If a government were to raise taxes to 100% or legalize slavery, it doesn't seem to me like you would consider it theft because it would be legal.
I haven't said anything about the system you lived under. I think everyone agrees that a system that does as you have described is an awful system.
I've never read or met anyone who thinks all humans are the same, like ants, or should all have the same outcome from their lives. Its a tired, lazy strawman. The kind I would expect from tecshare. If being illiterate was someone's choice then fine, but have you ever stopped to wonder if a huge majority of the illiterate people have not simply chosen to be illiterate because they are lazy? Has it ever crossed your mind that maybe (just maybe) many of these people are illiterate because they did not have proper access to education? Most rich people were born rich and most poor people were born poor. That has very little to do with the fact that people are different, have different potentials, and can be lazy.
The lazy child of a billionaire is much more likely to succeed than a child born to poverty in a war-torn area during a famine. Your life is set on a certain track before the age of 5.
